itpplication'file'd May 12, 1915. Serial No. 27,525.

To all whom it may concern:

Be it known that I, FRED J. STULP, a citizen of the United States,resident of Muskegon, in the county of Muskegon and State of Michigan,have made a certain new and useful Invention in Turn-Buttons; and Ideclare the following to be a full, clear, and exact description of thesame, such as will enable others skilled in the art to which itappertains to make and use the invention,

reference being had to the accompanying drawings, and to letters orfigures of reference' marked thereon, which form a part of thisspecification.

Figure 1 is a plan view of the invention; Fig. 2 is a side view of thesame. Fig. 3 is a plan View of a modification. Fig. 4C is a side view ofthe same. Fig. 5 is a plan view of a further modification. Fig. 6 is asection on the line 66 Fig. 5. Fig. 7 is a section on the line 77 Fig.5.

The invention has relation to turnbuttons, having for its object theprovision of an improved spring tension button, capable of economicalmanufacture, adjustable to uneven surfaces and that will not work loose.

The invention consists in the novel construction and combinations ofparts, as-

hereinafter set forth.

In the accompanying drawings, illustrating the invention, the numeral 2designates the button, which is provided at its ends with bearingportions 3, 3, to which are connected outwardly extending lateralinclined arms 4, 4, converging toward each. other, the button having adepressed middle portion 5, joined to said inclined arms by arms 6, 6,also converging toward each other, but oppositely to the first-namedarms, to which they are joined by spring bends, each of the arms 6, 6being of opposite inclination to that and shorter than the adjacentinclined arm 4, said middle portion being perforated at 7 for a securingscrew 8, and forming a bearing seat for said screw. The securing screwbeing tightened, the spring bends will yield, and the end bearingportions will have a more secure engagement with the work.

In the form of the invention shown in Figs. 1 and 2 of the drawings, thebutton is made from a single piece of wire, without waste of material,the converging arms 4, 4 and 6, 6 being present and in order that, whenthe securing screw is put under tension, there shall be no tilting ofthe bearing portions 3, 3, which squarely engage the work, a coil or aplurality of coils 9, 9 are made in the wire material of the button atthe bottom of the middle perforated bearing or seat for the screw.Tension of the screw will compress these coils and strain will bedistributed to the end bearing portions 8, 3 without tilting thereof.

In the form of the invention shown in Figs. 8 and 4: of the drawings,the button is stamped from sheet metal.

In both the wire and the sheet metal buttons the body of the button,formed by the outwardly extending inclined arms, the in wardly extendingshorter inclined arms and the middle screw bearing, is comparativelynarrow in width and of proper height to form a good finger or hand holdin turning the button. Both of these buttons are quite flexible andelastic, and the end bearing portions thereof will accommodatethemselves to abutting surfaces, as in the meeting rails of windowsashes, that are not even or of the same level.

In Figs. 4 and 5 of the drawings afurther modification of the inventionis shown, wherein the button is also stamped from sheet metal, theoutwardly extending in clined arms, the inwardly extending inclinedarms, the spring bends and the bearing seat for the screw forming partof a longitudinally extending raised or bowed central portion, thebutton having a lateral bearing flange at each side, extending from endbearing portion to end bearing portion and separated from said raisedcentral portion by a slit or cut 12 in the metal. In this form of theinvention the bearing end portions and the lateral. bearing flanges forma continuous bearing surface for engagement with the work. Lugs 14, 14are struck up from the raised central portion, for use as a hand orfinger-hold.

What I claim is:

1. A turn-button, comprising end bearing portions, lateral converginginclined arms, a depressed middle portion having a perfo ration for asecuring screw, and shorter converging arms and outer spring bendsconnecting said middle portion with said lateral arms.

2. A turn-button, comprising end bearing portions, lateral converginginclined arms, a depressed middle portion perforated for a securingscrew, and shorter converging arms and outer spring bends Connectingsaid middle portion with said lateral arms, the lateral arms and theshorter arms being comparatively narrow in width and of proper length toafford a good finger-hold.

3. A turn-button of wire, comprising looped end bearing portions,lateral converging inclined arms, a depressed coiled middle portionforming a springseat for a securing screw, and shorter converging arms10 and outer spring bends connecting said middle portion with saidlateral arms.

In testimony whereof I afiix my signature, in presence of two witnesses.
